$1500 emergency fund is LIGHT. It should at least be 3 months bare minimum living expenses. $1500 wont even cover a lot of people's rent/mortgage bill for one month.
Did you read his next point? Emergency fund is for when your car breaks and you have to take money out of savings to fix it.
When an emergency fund and X-months living expenses are compounded I really don't see the use of an emergency fund. Assuming someone has good enough credit to be able to borrow for short-term fixes in times of need.
